How to post on fb using php? - php

Question

I am using facebook apis to post on my testing account using php. The following code does the job for me and it works. If I log in with my account I can see the post, but if I use another account the post does not show. I have modified the privacy setting to public but still. I went to facebook's documentation,but I couldn't really find something to solve my problem. Can anyone help???
Thanks in advanced
function fb_post($post, $msg, $url, $pic) {
$temp_array = queryFBTable($post);
if (count($temp_array) == 0) return;
// initialize Facebook class using your own Facebook App credentials
// see: https://developers.facebook.com/docs/php/gettingstarted/#install
$config = array();
$config['appId'] = 'xxxxxxxxxxx';
$config['secret'] = 'xxxxxxxxxxxxxxxx';
$config['fileUpload'] = true; // optional
$fb = new Facebook($config);
// define your POST parameters (replace with your own values)
// see: https://developers.facebook.com/docs/facebook-login/access-tokens/
$params = array();
if(isset($temp_array['AccessToken'])) {
$params['access_token'] = $temp_array['AccessToken'];
}
if(isset($msg)) {
$params['message'] = $msg;
}
if(isset($url)) {
$params['link'] = $url;
}
if(isset($pic)) {
